04 - Control System
Control Panel
The control panel (display) is an integral component with
the Main Machine Controller circuit board The control
panel contains an LCD display, SmartKey reader for the
keyswitch, and a series of membrane switches for operator
control
SmartKey Reader (A):
The key reader provides a serial
connection between the SmartKey and the main machine
controller The controller checks the serial number of the
key to determine if it is authorized to enable the machine’s
operation
Different keys (operator-blue versus supervisor-yellow) have
different levels of access to the control system Operator
keys can be authorized/de-authorized for the machine,
so that each operator may have his or her own uniquely
identified key.
Power Switch (B):
When a key is in the key reader,
pressing the power button will boot up the controller and
turn the machine on Pressing and holding the button for at
least 1/2 second will turn the machine off
Display (C):
The LCD display provides feedback to the operator
with various text messages and graphic icons The main screen
shows scrub pressure, solution flow, detergent flow, speed, machine
hours, battery charge level, solution tank level, and any fault codes
The display will change as necessary to convey the appropriate
information
Information (D) and Menu Navigation (E):
Pressing the information switch enters or exits the system
menus The navigation switches provide navigation and entry for the menus, and will be discussed in greater
detail in
One-Touch Scrub (F):
When the One-Touch Scrub is selected, the brushes and squeegee are lowered to the
floor, and the solution solenoid is briefly activated to pre-wet the brushes. The scrub, solution, vacuum and
detergent (EcoFlex models) systems are all enabled and will start when the Drive Pedal is activated
Solution Switch (G):
The solution switch enables or disables the solution solenoid However, the solution
solenoid isn’t energized unless the scrub system is engaged and the machine is in motion
Vacuum Switch (H):
The vacuum switch turns the vacuum on and off, and automatically lowers or raises
the squeegee Because a hand operated vacuum wand is available as an option, the vacuum will operate even
when the operator is not in the seat and the seat switch is closed
Speed Limit Switch (I):
The speed limit switch sets the maximum speed of the machine to whatever the
current speed is in scrub mode to reduce driver fatigue. Allows full pedal deflection at the set speed.
Detergent Switch (J):
The detergent switch enables or disables the optional detergent pumps However,
the detergent pumps aren’t energized unless the solution system is also active, and the machine is in motion
Headlight Switch (K):
The headlight switch controls the optional headlights on the front of the machine
Brush Install Switch (L):
The brush install switch lowers the deck and spins the brush motors briefly to
aid in the installation of the brushes
Dust Guard Switch (M):
The side sweep switch controls the optional side sweep broom and optional dust
control pump and solenoid However, the side sweep system won’t be active unless the broom is lowered
(proximity sensor closed) and the scrub system is active
